Hello:
First at all: sorry my bad english. I'm Spanish, and my english is very bad, needs help from Google traslate and Disctionary. Never learn Englisn in school.
My name is Joseba Epalza, and i'm emulators developer from several years (about 1996), in past, did make Mr. Do's emulators saga in MSDOS, or LadyBug or City Connection, or even in Mame with my SpaceBall emulator.
More recently, did make Thomson M05 emulator in full basic source code (freebasic).
My goal today, is to make Star Rider Emulator (was one of my favourities games in the past). About one year ago, began to make StarRider emulator in Freebasic with my 6809 emulator in Basic. Make a huge advance in emulation, but several problems, (Matt, you must know this problems

) stopped me.
Video sincronization with PIA is very difficult, and to read all datas from footprint video is very complex. But, maybe, all together, joined in a group, was be able to get full data decoded.
In youtuve, uploaded sevearl videos, with my advance:
This is very interesting, because is for get data from footprint of video:
Does has any information about datas from video?
In my research, look for datas "frames number", "gravity on curves", "curve left or right" or "grade of curve".
This is an example of datas obtained from video:
Code:
227, 171, 16, 128, 128, 129, 128, 128, 128, 129, 129, 69, 139, 0, 33, 129, 116, 3, 152, 12, 32, 151, 128, 84, 255, 69, 253, 131, 245, 111, 232, 191, 128, 255, 2, 254, 133, 248, 23, 240, 95, 192...
226, 171, 17, 128, 128, 129, 128, 128, 128, 129, 129, 255, 139, 0, 33, 129, 116, 3, 152, 12, 32, 151, 128, 84, 128, 70, 1, 132, 245, 239, 231, 191, 128, 255, 2, 254, 133, 248, 23, 240, 95, 0...
225, 171, 18, 128, 128, 129, 128, 128, 128, 129, 129, 6, 139, 0, 33, 129, 116, 3, 152, 12, 32, 151, 128, 84, 255, 69, 253, 131, 245, 111, 231, 191, 128, 255, 2, 254, 133, 248, 23, 240, 95, 0...
Note then first number in sequence: 227, 226, 225, etc is a downcounter.
